Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
Your company uses Cloud Storage to store critical documents. You need to prevent accidental deletion or modification of objects for a retention period of 5 years. Which TWO features should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Object versioning
Object versioning preserves previous versions of objects, allowing recovery from accidental deletion or overwrite. Retention policies (bucket-level) enforce a minimum retention period for all objects. Bucket Lock makes the retention policy immutable. Object holds are per-object and can be removed. Lifecycle policies manage object transitions/deletion, not retention enforcement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Object versioning
Why this is correct
Versioning keeps old versions, enabling recovery from accidental changes.
- ✗
Object hold
Why it's wrong here
Object hold prevents deletion of a specific object but can be removed; not a blanket retention policy.
- ✗
Requester pays
Why it's wrong here
Requester pays shifts costs; does not protect data.
- ✗
Lifecycle rule to delete objects older than 5 years
Why it's wrong here
Lifecycle rules automate deletion; they do not prevent deletion or modification.
- ✓
Retention policy with Bucket Lock
Why this is correct
Retention policy prevents object deletion before the retention period ends; Bucket Lock makes it immutable.
